Abstract:

Objective To investigate the biological characteristics of middle aged people in Nanyang city, and to compare the left and right differences between them. Methods Twenty-five biological phenotypes of 495 healthy urban residents aged 45-59 years (230 males and 265 females) were collected and analyzed statistically using the method of physical fitness measurement and the intuitive determination. Results The right of the upper limb length, arm length, forearm circumference, grip, pedal strength, a-b ridge count in the men and women were higher than the left(P<0.05), while the length of foot, leg circumference, triceps skinfold thickness were less than the left(P<0.05). Finger ridge count (FRC), percent distance of axial triradius (tPD) in the male index of the right side were higher than the left. Systolic blood pressure, thigh skin fold thickness, and tPD left of the female were greater than right side(P<0.05). Arm circumference, and FRC of the little finger of the female were greater than the left(P<0.05). Other indicators were not statistically different. Conclusion There is a left and right side difference in the biological characteristics of the upper and low limbs of the middle aged people in Nanyang. The data provide a baseline information for the whole picture of the physical characteristics of the population.
